Avalanche Forecast
Regions: Glacier.
Excellent riding conditions have been observed at and Below Tree Line in sheltered areas. There's also been isolated large avalanches running to Valley Bottom from very steep alpine terrain. Early season conditions still exist at lower elevations.
Weather Forecast
Today: 5cm of new snow, winds will be moderate gusting strong from the SW, and the FL could rise to HWY elevation.
Tonight: 10cm of new snow, Strong SW wind, FL lowering to 600m
Saturday: Storms waning, we could see cloudy with sunny periods.
Sunday: Mainly cloudy
Snowpack Summary
45cm of new snow fell over the last 3 days, followed by Strong Southerly winds. The storm snow fell on varying surfaces; it mainly fell on previous storm snow, it also buried Surface Hoar size 3 in isolated areas. A 10cm unreactive very soft slab was noted up Connaught yesterday, similar conditions were also noted in the Asulkan thanks to an MCR .
Avalanche Summary
A significant skier accidental size 2.5 was reported via a MIN yesterday, it occurred just outside of the Park in Quartz Ck, failing on SH with wide propagation. Another MIN from Avalanche Crest observed SH beneath the storm snow, failing on steep unsupported terrain features. We obs 6 new slides in the HWY corridor avg size 2, with a 1 size 3
Confidence
Timing, track, or intensity of incoming weather system is uncertain
Avalanche Problems
Storm Slabs
45cm of storm snow fell over the last 3 days, combined with Mod-Strong SW winds. We obs a few natural avalanches in the HWY corridor to size 3. Just outside the Park a Skier accidental size 2.5 was reported via a MIN yesterday at Quartz Ck on SH!
- Avoid terrain traps, such as gullies, where the consequences of a small avalanche could be serious.
- Carefully evaluate terrain features by digging and testing on adjacent, safe slopes.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1.5 - 2.5
Persistent Slabs
Steep planar slopes should be avoided, especially at and just above treeline. Recent natural/human triggered avalanches, snowpack tests, and reports of whumphing indicate that this layer may still be triggered by the weight of a skier.
- Avoid shallow snowpack areas where triggering is more likely.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Possible
Expected Size: 2 - 3
